One of 20 molecules built of an amino group, a carboxyl group, and a uniqueside chain; proteins are constructed of combinations of these. these wereproduced in the urey-miller experiment, which demonstrated how complexorganic molecules could have formed in earth's early environment. amino acid microsphere phospholipid archaea

Amino acids.

Explanation:

Miller -Urey experiment was performed by creating the primitive earth condition in the laboratory. The main aim of this test was to determine the chemical origin of the life.

The electrodes was used to create the spark conditions and different gases like  water, methane, ammonia, and hydrogen. The product was obtained after some days of the reaction. The amino acids like glutamic acid, glycine, α-alanine and β-alanine was obtained from the product of this experiment.

Thus, the correct answer is option (1).
